1.启动服务

1.修改文件编码:
  dos2unix nfs.sh
2.启动
  sh nfs.sh start
3.重启
  sh nfs.sh reload
4.删除
  sh nfs.sh delete  

2.客户端

1.安装客户端
  sudo apt install nfs-client -y
2.挂载
  #方式一：容器ip
  kubectl get pods -o wide -ncbf
  mount -v -o vers=4,loud 10.244.0.79:/ /root/data/k8s/temp2/share/
  #方式二: service的ip
  kubectl get svc -o wide -ncbf
  mount -v -o vers=4,loud,port=32049 172.16.0.15:/ /root/data/k8s/temp2/share/
3.卸载
  umount /root/data/k8s/temp2/share/
4.验证是否已挂在
  df -h
